Even at 15 Euros I bet its way cheaper than a helicopter or electric VTOL aircraft

Oh, yeah, and it can and does handle a scale of traffic that a helicopter service obviously couldn't. I think each train takes about a thousand people and they're every ten minutes or something.

The "use helicopters for airport access" thing seems, at best, extremely niche.

Joby plans to expand way beyond airport access, it’s meant to be basically flying rideshare. The key enabler is they designed it to be quiet enough to not annoy everyone around like a helicopter, so that it would be reasonable to have this thing taking off from residential neighborhoods. JFK access is just a very visible first test run.

This thing will not be taking off from residential neighborhoods. Regardless of noise, like any manned VTOL aircraft it requires a large open area free of overhead obstructions (trees, wires).

And the notion that landing pads will be installed on the roofs of tall buildings is mostly a fantasy. Commercial or high-rise roofs are mostly already occupied with other machinery, and aren't designed to support the extra weight.
